And the lava-rock wraps do mot hold moisture like the older fiberglass based wrap.
Honestly, I think ceramic coating on headers are the equivalent of buying an extended warranty; it’s a way to tack on some extra profit on a deal but is usually useless.
Don’t get me wrong, ceramic coating can look really good and if it works for you then great.
Just my opinion and experience.

If you couldn't tell no difference between bare metal and coated headers then the coating you used isn't good. I recommend Jet-Hot 2500f. Its night and day difference, its not even debatable.
